Interesting thing, the Front Left read first, followed by FR, then RL and RR. So the system must know where they are sending information from. The module is in around the fuel filler neck.That's awesome; I had no idea they auto-synchronize with the vehicle. I always worried if I rotated my own tires, the sensors would think the front tires were the back, and vice-versa. Apparently that's not how that works, and the van figures out which tires are where, correct?
